Hello,
Just a quick reminder that this work to take stat100[4-7] out of service
will be going ahead next Tuesday morning, May 28th.
Please ensure that you have copied any important files to different stat
servers or to HDFS before then.
Feel free do get in touch with us at if you have any concerns about this
schedule.
Kind regards,
Ben

Hello,
I would like to upgrade stat1008 from buster to bullseye this Thursday
at approximately 09:15 UTC.
The upgrade is expected to take up to an hour, during which time
stat1008 will be unavailable for use. Work in your home directories will
be left untouched, so the impact should be low, especially if you are
using conda environments
<https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Conda>.
If this maintenance window is likely to cause an issue for you, please
do let me know and I can look to reschedule the work. We will also be
available after the upgrade, in case you experience difficulties with
the upgraded operating system.
After the upgrade, stat1008 will have new SSH host fingerprints, so I
will update this page SSH_Fingerprints/stat1008.eqiad.wmnet
<https://wikitech.wikimedia.org/wiki/Help:SSH_Fingerprints/stat1008.eqiad.wm…>
and provide some more help to get you reconnected.
Kind regards,
Ben
